Patriot Clinic officials said Friday that if they don’t raise funds quickly, they will be forced to close the center’s doors.

Chris Gregg, director of the clinic, served two tours of duty.

“I was in the first Gulf War; disarmed explosives,” he said. “I was EOD, landmines, package bombs, car bombs that type of thing.”

The horrors of war have haunted him ever since, taking a dramatic toll.

“I've been hospitalized five times for (attempted) suicide,” he said.

After receiving hyperbaric therapy at the Patriot Clinic in southwest Oklahoma City, he said, it changed his outlook and eased the emotional trauma.

“I was alive a couple months ago. I wasn't living at all, you know?” he said. “The fact that I'm able to enjoy my daughters – it's a big difference.”

The Patriot Clinic provides free treatments to veterans.

“We actually turn on all those stunned neurons. We regrow blood vessels into those damaged areas of the brain,” said William A. Duncan, vice president of the International Hyperbaric Medical Foundation.

The two-person chamber is on loan from a doctor in Texas. The oxygen is the costliest part of the operation.

“Our operations here run about $5,000 a month,” Duncan said.

Gregg said he is committed to saving the clinic that saved his life.

“I want the other family members to know that there are people that completely understand what they're going through, and we want them to be better,” he said.
